Or is your question how to properly import a. Write a program proj31.cpp that reads from user the length in feet and inches into two separate variables. The space between ' and n is important, although it might be better replaced with an underscore. After reading chapters 6, and 7, please solve the following problems: Problem 1: Convert to Meters Centimeters (40 points). The space and n/d are omitted for whole numbers, e.g. Just type this into the scale box in Print Preview and confirm with Enter. Where F feet, I inches, and n/d is fractions of an inch. Thus, I was trying to set the engineering scale at 1 inch = 50 feet & also set the dimensions of the page in LibreCAD.įrom: dellus ]ġ inch = 50 feet makes 1:600. I then wanted to calculate the buffer area. I imported the PNG image into LibreCAD so that I could create a 10 foot buffer around some objects on the scale drawing. I have a PDF of a scale drawing (at 1 inch = 50 feet) that I exported as a PNG using The GIMP. To unsubscribe from Set Engineering Scale of 1 inch = 50 feet, click here. And if you want to do a 11 feet, 6 inches just type in 11'6'. Just make it a habit of adding the correct symbol. However if you double click and put 6' after the 11' it will add the 6 inches correctly. If you double click the dimension and just type 6 it will screw up. If you reply to this email, your message will be added to the discussion below: For example if you input 11' it will set it to 11'-0'. As i*m born and raised in a country with uses only metric system, can't calculate it for you, but I guess you could find online calculator inches to feet from the net. By default, the value is '0' for both feet and inches although you can. Starting out, the control looks like the following: As you can see there, its just a GroupBox with two TextBoxes in it. Please use caution when opening attachments, clicking links, or responding to requests. In both versions, the class ('FeetInches') is a part of the control, so you wont have to worry about bringing that into your project just to use this. Subject: Re: Set Engineering Scale of 1 inch = 50 feetĬaution! This E-mail originated from outside the university. Metalworking is in mm, also with fraction of mm (8.000mm +008, -002).From: aman ] The second obvious one is woodworking, because in europe they tend to think in cm, while in the US still in inch. The most obvious one is architectural work, because it is huge (meter, centimeter) Would be useful to start collecting usecases? However 12900mm not telling me much, when I wanted a 5meter and 7meter length of wall with wall thickness taken into account. Enter feet and inches using the following format: feet-inches' or feet inches' or feetinches' You can separate feet, inches, and fractional inches with a dash, a space, or nothing. So for example if a wall needs to be 5m+7m+3*30cm, then I can put it in the length field, it is converted to 12900mm, and it is displayed it as is. What would be even better than doing conversions in QuickCalc would be if I could directly input feet-and-inches for any distance inputs. On a slightly related note: It would be tremendously helpful, if you could specify a unit via simple math, and the actual math would be preserved when you modify (displaying the result of course). QuickCalc hints at its ability to do length conversions, but I don't know how to input, say, 1' 3-1/2' and convert it to decimal feet. in sketch) in cm, freecad accepts it, but instantanously converts it to mm (freecad internal unit?), and it is displayed and when you modify it, also shows in mm. For example if you modify a line, then in the Data panel it should also display in cm if that is the preferred unit. I think one would expect to see units displayed everywhere the same. I think the easiest way out would be to allow to specify the desired unit in the Draft dimensions (and having a default in preferences). I tried to read on units in FreeCAD, but it is absolutely not clear, and looks like it is written as a brainstorming for developers. Units below 1 meter is displayed as centimeter: 30cm, 40cm, 15cm (wall thickness for example) Units above 1 meter is displayed as meter: 1.10 m, 1.20 m, 2.88 m Go to drawing B window, click on Paste icon or press CTRL+V and define a reference point. Go to drawing A window, select the green and red rectangles, click on Copy icon or press CTRL+C and define a reference point. Is it possible? In preference I can only change it permanently. Open drawing B without launching a second time LibreCAD. I would like to display units in different format then mm. I would like to scale everything permanently. Scaling via the Draft workbench scale utility createsĪ Scale (clone) object in the treeview. So I would like to scale everything by factor of 100. The drawing seems to be 100x smaller, then in real life (length of 20mm corresponds to 2meter). I converted the dwg to dxf file, cleaned up in LibreCAD, and imported into FreeCAD. I'm trying to follow the Arch tutorial here:
